Abstract
Air is separated into oxygen and nitrogen in rectification columns 28 and 30. A stream of nitrogen is withdrawn from the top of the column 30 through an outlet 54, is warmed to about ambient temperature by passage through heat exchangers 34, 46 and 24, and is then heated at a pressure in the range 2 to 7 atmospheres absolute by heat exchange in heat exchanger 56 with a hot stream of fluid initially at a temperature of less than 600 DEG C without said fluid undergoing a change of phase. The resulting hot nitrogen is then expanded in turbine 58 with the performance of external work, e.g. the generation of electricity.
